Abstract

Purpose

The Leap Motion represents a new generation of depth sensing cameras designed for close range tracking of hands and fingers, operating with minimal latency and high spatial precision (0.01 mm). The purpose of this paper is to develop virtual reality (VR) simulations of three well-known hand-based rehabilitation tasks using a commercial game engine and utilising a Leap camera as the primary mode of interaction. The authors present results from an initial evaluation by professional clinicians of these VR simulations for use in their hand and finger physical therapy practice.

Design/methodology/approach

A cross-disciplinary team of researchers collaborated with a local software company to create three dimension interactive simulations of three hand focused rehabilitation tasks: Cotton Balls, Stacking Blocks, and the Nine Hole Peg Test. These simulations were presented to a group of eight physiotherapists and occupational therapists (n=8) based in the Regional Acquired Brain Injury Unit, Belfast Health, and Social Care Trust for evaluation. After induction, the clinicians attempted the tasks presented and provided feedback by filling out a questionnaire.

Findings

Results from questionnaires (using a Likert scale 1-7, where 1 was the most favourable response) revealed a positive response to the simulations with an overall mean score across all questions equal to 2.59. Clinicians indicated that the system contained tasks that were easy to understand (mean score 1.88), and though it took several attempts to become competent, they predicted that they would improve with practice (mean score 2.25). In general, clinicians thought the prototypes provided a good illustration of the tasks required in their practice (mean score 2.38) and that patients would likely be motivated to use the system (mean score 2.38), especially young patients (mean score 1.63), and in the home environment (mean score 2.5).

Originality/value

Cameras offer an unobtrusive and low maintenance approach to tracking user motion in VR therapy in comparison to methods based on wearable technologies. This paper presents positive results from an evaluation of the new Leap Motion camera for input control of VR simulations or games. This mode of interaction provides a low cost, easy to use, high-resolution system for tracking fingers and hands, and has great potential for home-based physical therapies, particularly for young people.

Abstract

In his autobiography, Chen Shui-bian (1999, p. 40) condemned the Koumintang's (KMT's) corruption and praised the Democratic Progressive Party (DPP) for being free from money politics and corruption. The DPP fought the 1992 Legislative Yuan election campaign effectively on an anticorruption platform and used the same strategy in subsequent elections. If Chen Shui-bian had criticized the KMT for its involvement with “black gold” politics and had won the 2000 presidential election on his anticorruption platform, why was he and his family found guilty of corruption after his second term of office? The short answer is that even though he had promised to curb corruption, President Chen himself had succumbed to corruption after assuming office. In June 2002, Keesing's Contemporary Archives cited a poll in Taiwan that indicated that more respondents had perceived the DPP to be more corrupt than the KMT (Copper, 2006, p. 14).

Abstract

Purpose

This paper aims to analyse how both Lin’s birthplace identity and his Christian identity contributed to his fruitful public career and to ascertain which identity became the most significant.

Design/methodology/approach

Archival research is the main method used in this paper. The most important archives drawn from are the Daniel Tse Collection in the Special Collection and Archives of the Hong Kong Baptist University Library. Oral history has also been used in this paper to uncover more material that has not yet been discussed in existing scholarly works.

Findings

This paper argues that although Lin’s birthplace identity and social networks helped him to start his business career in Nam Pak Hong and develop into a leader in the local Chaozhou communities, these factors were insufficient to his becoming a respectable member of the Chinese elite in post-war Hong Kong. He became well known not because of his leading position in local Chaozhou communities or any great achievement he had obtained in business but because of his contribution to the development of Christian education. These achievements earned him a reputation as a “Christian educator”. Thus Lin’s Christian identity became more important than his birthplace identity in contributing to his successful public career.

Originality/value

This paper has value in showing how Christian influences interacted with various cultural factors in early Hong Kong. It also offers insights into Lin’s life and motivations as well as the history of the institutions he contributed to/founded. It not only furthers our understanding of the Chinese Christian business elite in early Hong Kong but also provides us with insights when further studying this group of people in other British colonies in Asia.

Abstract

Purpose

Christian-affiliated social groups and leaders have been active and vocal in movements advocating democracy, equality and social justices. Christians are also specular in the “July 1st Protest” in 2003 and “Umbrella Movement” in 2014. Are Christians, in general, more politically active in Hong Kong? This paper aims to examine these questions from a quantitative viewpoint.

Design/methodology/approach

This paper examines the effects of religion and other socio-demographic factors on both electoral and non-electoral participation based on data from the World Value Survey 2013 Hong Kong data set.

Findings

Interest in politics and education level are strong predictors of both electoral and non-electoral participation in Hong Kong. Confidence in government is negatively associated with political participation. Religious affiliation is not a predictor of any kinds of political participation. The effects of interest in politics are greater among Protestants and Catholics than people with no religion.

Research limitations/implications

While previous surveys show that Christians have a strong presence in political participation, the results suggest that being a Christian is not statistically related to a higher level of political participation. On the other hand, affiliating to Christian churches may provide necessary resources (e.g. networks, skills and knowledge) only to those members who are already interested in politics and thereby facilitate their political participation.

Originality/value

Based on national sample data, this study debunks the public perception that “Christianity is politically active” and suggests the possible role of churches in mobilizing politically interested members into political activities.

Abstract

Purpose

Assembly systems require uninterrupted components' availability to feed workstations. This paper aims to propose a methodology to help managers in evaluating and selecting the most suitable policy for materials delivery to the shop floor. The analysis focuses on three basic policies, namely kitting, just in time kanban‐based continuous supply and line storage, even including class‐based hybrid policies.

Design/methodology/approach

Descriptive models are developed to design components' delivery systems and to compute their performances. Empirical criteria are utilized to associate specific policies to components classes in order to implement customized hybrid line feeding policies. A case study is then included to exemplify the method application and to show its capabilities as a decision making tool.

Findings

Hybrid feeding policies may be preferable to a single feeding policy common to all components. This is shown in a representative case study. However, in general there is a priori superior method and only a comparison of alternative feeding policies based on objective performance measures can determine the best approach in specific industrial applications.

Research limitations/implications

The methodology is aimed at preliminary sizing and selection of alternative line feeding systems in deterministic environments. It is not intended for detailed performance analysis of assembly systems.

Practical implications

Production managers are given quantitative decision tools to properly select the components' delivery method at an early decision stage. This allows trade‐offs between alternatives to be explored in order to deploy customized feeding policies differentiated on components basis to better fit specific company requirements.

Originality/value

The paper extends previous descriptive models for line feeding systems and includes the possibility of hybrid policies.

Abstract

The Communist revolution in China has led to the appearance in this country of increasing numbers of Chinese books in Russian translation. The Chinese names in Cyrillic transcription have presented many librarians and students with a new problem, that of identifying the Cyrillic form of a name with the customary Wade‐Giles transcription. The average cataloguer, the first to meet the problem, has two obvious lines of action, and neither is satisfactory. He can save up the names until he has a chance to consult an expert in Chinese. Apart altogether from the delay, the expert, confronted with a few isolated names, might simply reply that he could do nothing without the Chinese characters, and it is only rarely that Soviet books supply them. Alternatively, he can transliterate the Cyrillic letters according to the system in use in his library and leave the matter there for fear of making bad worse. As long as the writers are not well known, he may feel only faintly uneasy; but the appearance of Chzhou Ėn‐lai (or Čžou En‐laj) upsets his equanimity. Obviously this must be entered under Chou; and we must have Mao Tse‐tung and not Mao Tsze‐dun, Ch'en Po‐ta and not Chėn' Bo‐da. But what happens when we have another . . . We can hardly write Ch'en unless we know how to represent the remaining elements in the name; yet we are loth to write Ch'en in one name and Chėn' in another.

Abstract

Purpose

This paper aims to examine ways in which multinational enterprises (MNEs) can secure knowledge assets across global operations.

Design/methodology/approach

The paper reports the results of a comparative case study. The practices of four MNEs are considered in conjunction with practices identified in the literature. A comparative company analysis is conducted using the resource‐based view of the firm.

Findings

The paper principally concludes that MNEs have several options for protecting knowledge assets. A set of seven recommendations are derived from the analysis.

Practical implications

The recommendations derived from the analysis could be beneficial for enterprises who do knowledge work in global settings.

Originality/value

The paper offers background and consideration for those companies with IP in global business environments. The background, analysis and recommendations add to the body of knowledge in this area.

Abstract

Purpose

This writing reveals Hong Kong’s role as the center of China research. Before Reform and Opening in 1979, the British colony was the only place in the world where all international China experts stopped over and obtained the latest and the most accurate accounts of PRC.

Design/methodology/approach

The paper analyzes how Hong Kong serves as the intellectual mecca through examining the lives of China scholars amid building up their international profiles. What prompted them to join the China field? How were their lives like in the British crown colony? This paper also unveils the roles of the two research institutions played on Communist China studies: University Services Center (USC) and Union Research Institute (URI). In addition to relying on archival correspondences, personal interviews were also conducted in the last two years.

Findings

Despite being the mecca of PRC research, Hong Kong was not the first destination for most aspiring China scholars from the West. Most of these Western scholars did not even plan to devote their whole working lives to the study of China. Through luck, draft avoidance and generous grants from Ford and Carnegie Foundations, these young men and women became internationally iconic figures of East Asian research. To complete their Ph.D. theses and subsequent China-related projects, Hong Kong was a “must-go” destination for them. Under the full protection of the Union Jack, these scholars enjoyed the freedom to speak, write, research and publish. God blessed Hong Kong with such a unique political status amid the Cold War.

Originality/value

155 Argyle Street was the Art Deco compound where Red China experts produced most groundbreaking scholarships. It was not only a two-story structure where they acquired their first-hand resources but a platform where any China-related topics were discussed openly under the auspices of British colonial rule of law. Despite claiming themselves as apolitical, both USC and URI were products of US containment policy against communism. Even so, the colonial government never prohibited the two’s operations. Through this paper, readers will also discover how young men and women became inspired into a career in China studies.

Abstract

Investigates the evolution of mass rapid transit (MRT) in relation to the Hong Kong market and analyses the effect of surrounding land values. Outlines the unique features of Hong Kong which make an urban railway system ideal and discusses the changes brought about by MRT. Summarizes the growth of commercial development on Hong Kong island and gives case studies on the Admiralty, Sheung Wan and Taikooshing/Kornhill areas in respect of their development with the advent of MRT. Notes that the shortening of travelling time for workers has increased demand for, and hence the price of, sites immediately adjacent to MRT stations.
